In user testing, website use on mobile devices got very low scores, especially when users accessed “full” sites that weren’t designed for mobile.

Doesn’t surprise me. Websites are usually designed by designers and often they focus on how it looks then how it works. This is bad enough when using a browser on a computer, but when it comes a mobile device as Jakob’s study shows, it doesn’t work well or doesn’t work at all.

The number of mobile devices is increasing and the amount of mobile web usage is going up as well. Designers of websites and e-learning content need to consider mobile devices now rather than wait until it is too late.
